ABOUT JEWELRY PATINA AND PROTECTION

HOW TO CARE PATINA ON METAL JEWELRYI write this post for my customers.

On my jewelry I use LOS (Liver-of-sulfur) or black patina, both make gray/black color and depending of metal, shadows can be like dark gold or purple colors. It is necessary to know that patina is not permanent. Patina is very tiny layer on surface what must be protected for durable color.

Each patina on any jewelry is like color on jeans, with time fades. Oxidized durability also depends on the PH skin. If a person has a some illness and drinking strong medicines then the blood have more acidic and has more toxins. Toxins come out on the surface of the skin and create a reaction with metal jewelry.
In this situation the black / gray patina becomes pale a lot faster. If the person sweats, sweat also makes reaction on the surface of metal jewelry.
Please use the perfume, hair spray and deo spray before putting jewelry. The skin needs to be dry when you put jewelry because the perfume, hair spray and the deo-spray make a chemical reaction. Jewelry that is worn on a clothes, not directly on the skin, will have a longer patina color. Do not wear jewelry on the beach / pool, never during bathing. Remove the rings when you wash your hands or work in the kitchen. For rings it is important not to wear them when doing physical work that may cause scratches on the surface of the ring.
If you follow these instructions, patina on your jewelry will last longer.
Only gold, platinum and others noble metals do not oxidize, so do not be sad when you notice the color changes of your silver, especially copper and brass jewelry, as this is their characteristic. In any case, silver, copper and brass are healthy metals, not toxic.

I can re oxidize jewelry what you are buying at my web shop at any time, please contact me for this. You will pay only shipping cost in both direction or you can visit your local jewelry artist / shop to do that for you * - *

ABOUT RENAISSANCE WAX

Renaissance Wax was developed in the British Museum research laboratories in the early 1950s.

The wax is uniformly and lightly applied to the surface, then lightly buffed with a smooth hairless fabric to gain gloss. Where a shape is needed, for surface with relief, a brush can be used. It is also used in jewelry making to preserve the patina of the metal.
Obviously the application technique and tools must be appropriate to any specific needs of the item being treated. For flat surface you can use wax with finger.

Renaissance Wax is a brand of micro crystalline wax polish that is encountered in antique restoration and museum conservation. It is not appropriate for all materials, and is most safely used on metal objects. However, it is also used for the polish and conservation of organic materials such as wood, ivory, tortoiseshell, and gemstones. Renaissance Wax is sometimes used by reenactors of historic swordsmanship to protect armor and weapons. Waxes are more protective and longer-lasting than oil, especially for swords and helmets that are frequently touched by human hands. It has recently been introduced in the world of guitar building, as a finish that protects and gives color to the wood.

Wax coatings for conservation are most widely, and least controversially, applied to metals. This has several objectives: to produce a barrier that excludes moisture and oxygen from the metal surface, to ensure against further introduction of contaminating elements by handling, and to provide a protective layer over anti-corrosion undercoatings. Waxes are not permanent, though, and will attract dust and lint over time, necessitating removal of the dirty wax.
P.S. Part of the text I've taken from Wikipedia: https://en.wikipedia.org/wiki/Renaissance_WaxABOUT GREEN COLOR ON THE SKIN

The green color left by copper and brass on the skin is not toxic and easily removed with soap or alcohol. This is a normal reaction that will be more intense in people who have more toxins in the blood, their blood is acidic. This acid comes to the skin surface and creates a reaction with the metal.
Green color on skin is also indicator for possible illness.

ABOUT ACID BLOOD AND PEARL JEWELRY

How much acid in the blood is powerful in creating a reaction with the things that we wearing is the fact that people with diabetes should not wear pearl jewelry. Pearls are porous and skin toxins easily penetrate into them and completely destroy them.

ABOUT ZAPON LACQUER

My last way to protect the surface of metal jewelry is Zapon lacquer, well known in the art world. Has a micro drops that are finely dispersed, creating an invisible matte protective layer.

I hope this post has provided enough information on protecting the surface of jewelry. If you have any questions, feel free to contact me :)
